# Why Choose Churnkey Over Churn Buster?

## Overview

Churnkey is the modern Churn Buster alternative. It supercharges every aspect of customer retention, treats your customers with respect, empowers your internal teams, and accelerates revenue growth.

Churn Buster and Churnkey are independent companies and competing platforms. Churn Buster launched in 2013 with a focus on failed-payment recovery (dunning). Churnkey was built later as a complete retention platform spanning [Cancel Flows](/feature/cancel-flows.html.md), [Payment Recovery](/feature/payment-recovery/index.html.md), [Reactivations](/feature/reactivations.html.md), and [Adaptive Offers](/feature/adaptive-offers.html.md). Today both platforms cover Cancel Flows and failed-payment recovery. The difference is how far each one goes.

Churnkey offers a free start, pricing tailored to each business, and an ROI guarantee.

## Retention Is Not a Feature, It Is a Craft

Churn Buster recovers revenue. So does Churnkey. The difference is in what was not left unfinished.

- **Deeper Cancel Flows** — Both products offer Cancel Flows. Churnkey takes them further: [Session Recordings](/feature/session-recordings.html.md) show exactly where customers hesitate, a single toggle translates every flow, and a Pause Wall, Trial Extensions, and seat handoff offers give each customer a reason to stay.
- **Feedback mapped to revenue** — Churn Buster has a version of feedback analysis, but it does not map feedback to MRR. With Churnkey's [Feedback AI](/feature/customer-insights-ai.html.md), you can see exactly which feature request is tied to how much revenue, and prioritize accordingly.
- **Depth and intent** — Underneath it all sit two things. Depth: how far each feature has actually been taken. And intent: Churnkey was built specifically for product-led companies, not adapted from ecommerce.

Most retention tools are built to be sold. Churnkey was built to work. And in retention, every small detail compounds and saves revenue.

## Our Typical Customer

- Lowers cancellations by up to 54%
- Recovers up to 89% of failed payments
- Reactivates up to 34% of subscriptions
- Increases customer LTV by 28%
- Boosts MRR by 14%
- Ups expansion revenue by 9%

## Outcomes for High-Volume Subscription Businesses

### Save More Cancelling Customers

Churnkey saves 54% of customers who intend to cancel. That is an average, not an outlier. Churn Buster does not disclose its averages. Churnkey tracks this number and ships updates that help each customer move the needle.

### Recover More Failed Payments

Churnkey recovered 70% of all involuntary churn it detected, an average across its entire customer base rather than cherry-picked outliers, and one of the highest recovery rates in the industry. Churn Buster shares no benchmark data.

### No Unnecessary Hand-Holding

Churnkey offers human support, recurring strategy calls, and an ML-based [Account Agent](/feature/account-agent.html.md) that finds opportunities humans can't. The difference is that the product doesn't need hand-holding to perform. Churnkey's position is that Churn Buster leans on human support to compensate for what its product can't do on its own.

### Intelligent Products That Are Self-Aware

Every cancelled subscription is a negotiation you lost. Adaptive Offers uses AI to find the right discount for each customer, maximizing saves while protecting margins. [Precision Retries](/feature/payment-recovery/payment-retries/index.html.md) combines rule-based and self-improving logic to recover passive churn. See the [Intelligence Suite](/intelligence/index.html.md).

### Analyze Messy Product Feedback at Scale

Churnkey gathers a large volume of data at delicate customer touchpoints. Feedback AI categorizes all of it for your teams and maps it to revenue lost.

### Understand Your Churn for Free

Connect your payment provider to break churn down by revenue vs. logo churn, cohort analysis, new vs. old churn, and more. [Churn Metrics](/churn-metrics/index.html.md) is available free in Churnkey. Churn Buster offers nothing comparable.

## Why Teams Choose Churnkey Over Churn Buster

The details compound. This is what that looks like in practice.

1. **Security you can (actually) trust** — Billing data is sensitive. Churnkey is GDPR and SOC-2 Type I compliant. Churnkey states that Churn Buster has no security certifications.
2. **Features that go all the way down** — Filter dunning emails by failed payment code. Send emails in a customer's local timezone. Run A/B tests that tie to MRR recovered. These details compound into real revenue recovery.
3. **A product that respects your processes** — Churnkey products are modular, so teams can build something unique to them. Churn Buster's biggest differentiator is pairing customers with people who have "10 years of retention experience", which can mean receiving the same advice as every other customer.
4. **True innovation that keeps adding revenue** — Automatic compliance, localization, custom attributes, discounting future payments, and more are table stakes in Churnkey. Churnkey invests more in research and development than its competitors.
5. **Transparent pricing, built for ROI** — Churnkey discloses pricing publicly and is transparent about how it scales, so you can estimate on your own. Churn Buster keeps pricing behind a demo call.
6. **Stripe's retention partner of choice** — Churnkey is a certified premium Stripe partner. Stripe recommends Churnkey to its customers and runs co-marketing campaigns alongside it. Churnkey goes deep with Stripe, Chargebee, Paddle, and a few others.

## FAQ

### Is Churnkey Based on Churn Buster, or Are They the Same Company?

No. Churnkey and Churn Buster are independent companies and competing platforms. Churn Buster launched in 2013 focused on failed-payment recovery. Churnkey was built later as a complete retention platform: Cancel Flows, Payment Recovery, Reactivations, and Adaptive Offers in one place. Today both platforms cover Cancel Flows and Payment Recovery.

### What's the Difference Between Churnkey and Churn Buster?

Both platforms cover voluntary and involuntary churn, with Cancel Flows and failed-payment recovery. The difference is depth. Churnkey records every cancel session, translates flows with a single toggle, adds a Pause Wall, and maps each cancel reason to MRR with [Feedback AI](/feature/customer-insights-ai.html.md). And Churnkey publishes its results: a 54% average save rate and 70% recovery on involuntary churn detected.

### Do I Need Both Churnkey and Churn Buster?

No. Both platforms cover Cancel Flows and Payment Recovery, so running the two means paying twice for the same jobs. Most teams replace Churn Buster outright when they switch.

### How Do Save Rates Compare Between Churnkey and Churn Buster?

Churnkey saves 54% of customers who intend to cancel, the average across all customers rather than a cherry-picked best case. Churn Buster doesn't publish its save rate. For Payment Recovery, Churnkey averages 70% recovery on involuntary churn detected. Churn Buster shares no benchmark data.

### Does Churn Buster Have Cancel Flows?

Yes. Churn Buster offers Cancel Flows with cancel-reason surveys, targeted offers, and A/B testing. Churnkey's [Cancel Flows](/feature/cancel-flows.html.md) go further: session recordings show where customers hesitate, a single toggle translates every flow, and a Pause Wall, Trial Extensions, seat handoff offers, and anti-gaming cooldowns come built in. So the real question isn't whether each tool has Cancel Flows. It's how far each one takes them.

### Is Churn Buster Cheaper Than Churnkey?

Churn Buster doesn't publish pricing; it sits behind a demo call. Churnkey publishes pricing transparently with a public ROI calculator. A direct cost comparison is difficult, but on per-feature value Churnkey covers materially more retention surface for what teams typically pay. See [Pricing](/pricing/churnkey-pricing.html.md).

### What's the Migration Path From Churn Buster to Churnkey?

Most teams do a parallel run: Churn Buster stays live for a two-week overlap while Churnkey is configured against the same billing provider, then a flip-the-switch cutover. Total integration averages 35 minutes. Churnkey supports Stripe, Chargebee, Paddle, Braintree, and Maxio out of the box.
